Abstract
This invention provides an ultra-thin strip extrusion die, belonging to the field of extrusion die technology. The extrusion die includes a die head, a die core, and a die base. The die core is fixed in the die base, and the die head is fixed to the die base. The die head, die core, and die base are respectively provided with a die head extrusion cavity, a die core extrusion cavity, and a blanking hole. The die head extrusion cavity and the die core extrusion cavity are opposite to each other, and the die core extrusion cavity and the blanking hole are opposite to each other. This extrusion die extrudes the strip multiple times, gradually extruding it into the desired shape. The stress on the extruded strip is not severely concentrated, avoiding strip cracking. It can extrude ultra-thin strip and produce qualified products, filling a gap in the technical field of tin alloy ultra-thin strip extrusion.
